To all whom it may-concern:

Be it known that we, Joan-n B. Lose and i FRANK Tooo, citizens of the United States, 3

in .the count y of (look and State of Illinois. have invented e'ertnin new and useful lmprovenients in Radiators! for Automobiles and for other. Purposes-mi which the following is a specification.

While the .invention is above termed a radiator for automobiles, it is manifest that it nut be used for other specific purposes medium mssing;

w iieh .a circulating to give out its heat to the'sarroum ing atniospln-m, and in this as wet or eonsideration of the device it n|ay used for heating the surrounding air of a room of a lnuldingythua' eonservin the heat. instead of, as in the ease of a rut iator or under for automobiles, simply dissipating it in .the

eienev, in the ease of an nutmnohile radiator i8, 0 course, the-ehief ohjwt-uiu'ual at, and otherilnlmrtant ohjertsare, to produce a radiator ofpubetanttal and durable eonstrueand thmtbilit'y, while at the same time retuirin a minimum amount of sheet metal 08ml ly eoimeryin' its eonslrm-tion, thereby not onl v-'aemmplishhii: a saving in their-o t of the metal but minliuing' the radiator as a whole to as light, wright as is consistent with the necessary strength, durability and eieneyr 'lhere is'u familiar and popular type of radiator which is, known as the.lmney comb. I 'l'l|t-st':,|'adiators have water. tubes extending from the 'upper .to the lower hear'rrmnl so pared apart as to leave between them horizontal pa'ssawexteudim'g from front to bat k ol' the radiator, for net'- lnittiug the passage of air as- .the nmrhine progresses.

Another and very in|p:a-t-ant-=ohjert of the inventionis to 'a-ovide'a radiator improved in its eonstna-tmn aith res n-ct to thevfarilw iich may ilt't'fllltl! leak ordauurgeal may be removed, repaired.. am reversed, or a newtuhe or tuhes suhstituted-witlnatt distal-bin the others. or disas embling auhstanl ially aii of the -hnnd,t lt V maybe and preferah parts and rebuilding theen tire radispeeilieation'and in which:

All oft-he tubes are of similar construction. The parts or featuree at the oppoaite ends of each tube,

V which enter into the construction of thelock joints, are made in reverse of each other no that no matter which end of a given tube it reaented in a given direction its lock 'oint turea will be aimilarly presented.

These bottom walla, H, of the channels are provided with small perforations, Lone object of which is to reduce weight, while another object is to facilitate-the passage of the heat't'rom the walls of the water tubes directly into the horizontal air passages, without objectionubly or seriously ilu miriug the strength of' the sheet of \vlucht 1e channels are formed. To this'cn'd-the perforations.

Loo ing at Fig. 3, which is a aection' taken; in.a vertical plane extendin v from side to' aide of the radiator, it ii'ill seen that at the open sides of the channels there'is but one thitltl'slltlfltft of metal betwee'ciltlhe wat'er amageaaii ,1 its air pasta w ie at t e liottomii of the channels dig in a double thickness of metal. this double thickness were continuedquite-to the front sides or edges of the tubea, the-face of the radiator rculcil as an individual cnt-ity separate and' part from erery other tube. an it is thus st'iugnia'hcd -fro'm those radiator-Kt rilct'ures. i which adjacent walla of ud'accnt water nets oi pax ages are integral or so Ionn- Rt'ttd that both walls ofnuy si'n le water net 01' pnsmpe' cannot be remove without l the same time removing one of the-walls teat-h of the two' ldjacent water dncta'or usages.
